This invention relates to improvements in hose holders and, morespecifically, to an adjustable holder for a cooling fluid hose used inconnection with a horizontal boring machine tool or the like.

The primary object of the present invention is the provision of a deviceof the character described which will safely hold a hose in adjustedposition and which will prevent any dislodging of the hose due tovibrations or due to a changing pressure of the fluid which passesthrough the hose;

Another object of the present invention is the provision of a device ofthe character described which will firmly grasp and hold the hose fromfour sides and whose lateral pressure upon the hose will increasewhenever its pressure from above and below increases, so that the hosecannot be squeezed more or less flat from two opposite sides; I

Still another object of the present invention is the provision of adevice of the character described which is simple in construction, easyto manipulate, and inexpensive to manufacture, but which is well adaptedto withstand the rough usage to which devices of this kind areordinarily subjected.

Further objects of the instant invention reside in any novel feature ofconstruction or operation or novel combination of parts present in theembodiment of the invention described and shown in the accompanyingdrawing whether within or without the scope of the appended claims andirrespective of other specific statements as to the scope of theinvention contained herein.

In the drawing:

Figure l is a side elevation of a preferred embodiment of my inventionas it appears when used in connection with a single end horizontalboring machine;

Figure 2 is a vertical cross-sectional view of the device drawn at anenlarged scale;

Figure 3 is a plan view of a detail; and

Figure 4 is a side elevation of the detail of Fig. 3.

Similar numerals refer to similar parts throughout the several views.

In the drawing, the numeral I denotes a matool table upon which rests atool support 2 that carries a motor 3 and a revolving tool 4. A slidingtable 55, holding the work W, is in a well known manner provided withT-shape'd members 6 which engage longitudinal T-slots l in the table l.The parts I to l inclusive forming no part of my present invention areillustrated in the drawing only for aiding in the description of myinvention.

A supporting shaft 8, which has a threaded portion 9, extends upwardlyfrom the sliding table 5, and can be vertically adjusted by screwing itmore or less deeply into the table 5. A nut l0 allows a retaining ofshaft 8 in an adjusted position, and the table is provided with alongitudinal slot ll, so that the lower portion of shaft 8 can beextended below the lower surface of the sliding table 5. The upperportion of shaft 8 is connected to a curved clamp l2 whose extremitiesare provided with'horizontal lugs to which upwardly extending threadedbolts I! are secured. A second clamp l3, which is of substantially thesame shape and size as is clamp I2, is arranged above the clamp l 2; andthe bolts I! are extended through the lugs of clamp l3. The clamps l2and I3 are of considerable width, so that a hose I4 can be held safelybetween them. In order to make it possible that hoses of differentdiameters can be held by one and the same clamps I2 and I3, I prefer tomake the curved portions of said clamps of a larger radius than is theouter radius of a medium sized hose ordinarily used for the conductingof cooling fluid to the rear of the work W.

Since such oversized clamps grasp the hose It only partially, I preferto provide also for a lateral grip of the hose [4. I prefer to carry outthis feature of my invention in the manner shown in Fig. 2, where itwill be seen that two wedge members l5 are placed between the clamps l2and I3 in such a manner that the tapering sides of each wedge member l5are adjacent the inner side of the corner portions of the clamps l2 andI3, so that the wedges will be forced toward each other when the clampsl2 and I3 are being pressed toward each other by tightening of thescrews [1. The wide front portion of each wedge I5 is curved (Figs. 2and 4), and from the narrow portion of each wedge extends a longitudinallug which is provided with a slot l6. These wedge lugs are locatedbetween the lugs of the clamps l2 and I3, and the bolts l! are extendedthrough the and of a vertically adjustable supporting shaft connectingone of said clamps to a base, a pair of wedges from whose narrowportions slotted lugs are extended which are located between the lugs ofsaid clamps, and threaded bolts connecting the clamp lugs to each otherand extending through said wedge lugs, all substantially as set forth.

2. In an adjustable hose holder which comprises a pair of curved clampsfrom whose extremities lugs are extended, the combination of a pair ofwedges from whose narrow portions slotted lugs are extended which arelocated between the lugs of said clamps, with threaded bolts connectingthe clamp lugs to each other and extending through said wedge lugs, anda vertically adjustable supporting shaft connecting one of said clampsto a horizontally shiftable base plate, said wedgesbeing arrangedbetween said clamps in such a manner that their tapering sides areadjacent the inner sides of said clamps so that the wedges will beforced toward each other when the clamps are being pressed toward eachother, all substantially as described.
